Many of the signs and symptoms of Hunter syndrome overlap with common childhood complaints, but clinical suspicion can be triggered by particular symptom clusters that are unlikely to appear in an unaffected child.1 As it is often the pediatrician who recognizes an underlying problem connecting the seemingly unrelated signs and symptoms that a patient has, increased awareness of MPS II is a critical factor in early diagnosis and referral.1

A newborn infant who has Hunter syndrome may appear unaffected in the first months and years of life, but between the ages of 2 and 4, physical abnormalities begin to emerge and, in some cases, cognitive impairment may develop.2

Management

After a confirmed diagnosis of MPS II, the pediatrician has a key role to play in the multidisciplinary management of the patient.1 Patients and caregivers are often overwhelmed with the number of different pediatric specialists that are involved in their care to manage their specific symptoms.1 The pediatrician can help facilitate care among these many specialists and provide a consistent medical home for the patient.1
